I love the sound of the 12 string guitar It has a full sound that works well for both Blues and Spanish (Tejano music) The state of Texas has both. Texas, like Mississippi, is one of those states that has incredible music and incredibly ugly politics.
The 12 string guitar came from Mexico It was used by street singers. Lydia Mendoza was one of the most talented and popular singers. Mal Hombre - loosely translated - Bad or Evil Man
Here's another clip:
It has been postulated that African Americans Blues Musicians heard these musicians and picked up the 12 string guitar. Leadbelly was the most popular and well known. He was able to obtain a governor's pardon, not once but twice!
Here is a "newsreel" with John L. Lomax.
